化工原理课程线上线下混合式教学实践与效果评价

Practice and Evaluation of Blended Teaching Mode for Chemical Engineering Principles

针对农林院校化工原理课程知识点多、课时少、实践性不足等问题,设计、实施了线上线下混合式教学模式,并对教学效果评价进行了研究。对比实验研究结果表明,混合式教学模式对学生学习效果有较好影响,实验班学生成绩的平均分、及格率及优秀率均显著高于对照班,表明线上学习对线下学习有促进作用。采用问卷调查法研究了学生对网络平台、线上教学资源、教学模式及自我参与完成度的评价,访谈结果也表明学生对该混合式教学模式较为满意,总体满意度达到97.56%。

The course of Chemical Engineering Principles in the University of Agriculture and Forest has many knowledge points and less class hours,which result in the insufficient cultivation of practical ability.In this paper,a blended teaching mode for Chemical Engineering Principles was designed and practiced,and the evaluation of effectiveness was studied.The results of comparative experimental research indicate that the blended teaching model has a good impact on the learning for students.The average score,pass rate,and excellent rate of students in the experiment class are significantly higher than those in the control class.Learning online has a promoting effect on learning offline.The survey by questionnaire was employed to study the evaluation of online platforms,online teaching resources,teaching modes,and self-participation completion.The results of interview also showed that students were relatively satisfied with the blended teaching mode,with an overall satisfaction rate of 97.5%.
